Kora had a profound connection to her race memory, much like Tal. They had been granted new life thanks to Lind and Lord Skinwalker. The latter's Inheritance was a true memory made once more and Lind's interactions changed her and Tal's fates.
Thus, the race memory she could access was far greater than normal.
She had become a Crystal Tier as easy as breathing. It was like she had innately understood how to fight back thanks to the ancestral rocs that guided her.
Tal had put on a display of her impressive stone hide that seemed to become impervious to lightning until she faced the tribulations tied to her Laws and comprehension.
Even so, Kora had a plethora of knowledge most had lost during the Cataclysm and the Fiend War events.
